Abstract
Air distribution plays a significant role in the mosque design process because the building inhabitants anticipate acceptable indoor air quality. The temperature, speed, direction, and volume flow rate of indoor air, might make the worship uncomfortable if not designed well. It makes no difference how efficient the ventilation system is if the air is not evenly distributed. This study aims to study the air distribution for the best energy consumption by comparing three cases of variation in inlet and outlet locations. Furthermore, to avoid local temperature differences by extracting warmed and contaminated air before dispersing across the space. The impacts of inlet and outlet air position to room heat sources on air distribution and thermal comfort were investigated using Computational Fluid Dynamics CFD approaches. The result shows that inlet and outlet location significantly affect mosque air quality.
